sTovE-HOLE COVER.

SPECIFICATION forming part of Letters Patent No, 369,040, dated August30, 1887.

Application filed December 9, 1886. Serial No. 221,104. (No model.)

To all whom 'it may concern:

Beit known that I, HARRY CURRIER BAKER, a citizen of the UnitedStates,and a resident of the city of Salt Lake, in the county of SaltLake and Territory of Utah, have invented certain new and usefulImprovements in Stove- Hole Covers, of Which the following isaspecification.

My invention relates to covers for the potholes in stoves, the coverhaving apertures therein controlled by a sliding plate mounted on saidcover, and the main object of my in'- vention is to provide saidapertures with independently-operated sliding plates.

My invention will be hereinafter fully. described, and its novelfeatures carefully defined in the claims.

In the drawings which serve to illustrate my invention, Figure lis aplan view of a pothole cover for a stove constructed according to myinvention. Fig. 2 is a transverse section of said cover, taken on line 22 in Eig. l. Fig. 3 is a perspective view of one of the sliding platesof the cover detached. Fig. 4 is a plan view of the retaining disk orkeeper detached. Fig. 5 is a plan view of a pot-hole cover for a stoveconstructed according to my invention and provided With stops to limitthe movements of the slides. This is the preferred method or manner ofmaking the cover, 'although these Fig. 6 is a view of the under side ofmy improved cover, showing the provision forand manner-of ap'- plyingthe lifter for removing the cover from the stove and the guide-ribsformed on the under side of the cover for strengthening the same and forguiding the tip of the lifter into position and preventing lateraldisplacement thereof.

Referring mainly to Figs. l, 2, 3, 4, and 6, A represents the pot-h olecover or main plate, Which has formed i'n its upper surface a largecircular recess or depression, c, in the bottom of Which are formed oneor more (preferably two, as herein shown) sector-shaped apertures, a. Atthe center of recess a, and in its bottom, is formed an annular grooveor recess, a2, and at the outer margin of recess ,and in its bottom, isformed, vby preference, an annular groove, c, with an inclined orsloping bottom. On the outer margin of the cover A, on its under side,is formed, by preference, a flange, a4,

and also chipping pieces or projections a5,

(three or more,) which project down a little This latter ange y Waybeyond the flange a4. is only employed to impart thickness to the plateat its edge, the outer margin of the plate being made quite thin for thesake of lightness. The chipping-pieces a5 serve a double purpose. Theyserve to raise the edge of the cover slightly above the rabbeted bearingin the stove-top, (seen in dotted lines in Fig. 2,) thus leavingair-spaces surrounding the cover, which will prevent the breaking of thestove by too sudden expansion of the cover, and, inthe second place, byproperly reducing these chippingpieces With a file or chisel the covercan be made to fit flush in stoves having shallower rabbets than thosefor which the cover was originally intended-that is to say, thesechipping-pieces supply a convenient means of fitting the plate torabbets of different depths. On the lower face of plate A is alsoformedthe circular pendentguide-flangec, which depends into and fitsloosely in the stove-hole.

B B are two like sector-shaped sliding plates mounted in the recess c ofthe cover A. These each have a pendent flange, Z, of step-like shape,formed on their margins or edges,which t loosely in the annular recessor groove a, and each has also on its lower outer margin a beveled ange,b', which fits into the annular beveled groove ci in the bottom ofrecess a.. These flanges or thickening. of the edges of the slides areto prevent the slides from Warping and to strengthen them.

Over the depressed inner flanges, I), of the slides B, Where they restin groove a2, is arranged a keeper-plate or disk, G, which is securedrigidly to the cover by means of a bolt and screw, c. I prefer to employa bolt, as shown, providing in the under side of the cover a recess toreceive the nut c of said bolt. This construction permits the slides Bto be readily 0n the cover over said aperture, thus permitting the fireto reach or act directly upon its bottom. Each aperture having its ownsliding cover, the degree of opening in the cover may be regulated verynicely, and may be varied at will. Of course this invention is designed,mainly, to accommodate utensils that do not fit the stoveholes, or arenot designed to fit such holes.

On the under side of the cover are formed pendent radial ribs ai alongthe margins of the apertures a'. These ribs are to impart strength tothecover and preventit from cracking between said apertures. They are bestseen in Fig. 6.

I do not employ a recess for the lifter; but in removing the cover theend of the lifter D in Fig. 6 is passed down through one of theapertures in the plate, and its tip d takes under the depressed centralpart of the plate. T0 prevent the tip d from slipping laterally, it isarranged to take between two guideribs, as, on the under side of thecover. rIhis construction and the mode of applying the lifter are seenin Fig. G. My cover may, however, be provided with a special recess orsocket, of the usual kind, to receive the end of the lifter.

In Fig. 5 (which is otherwise the same as Fig. l) are shown radial stopsa in the nature of ribs formed on the upper face of the cover. Theseribs extend across the recess a, from the outer margin of same to theedge of the annular recess a, and are, by preference, iiush with thegeneral level of the plate. These stops limit the movements of theslides B B in both directions, and this is one of their functions; butthey have another function,which is to furnish a support at one side forany small vessel or utensil set on the cover. Without these ribs orstops a very small vessel would be apt to tilt toward that side. Forthis reason I bring them up flush with the general level of the cover.

In Fig. 6 four chipping-pieces, a5, are shown equally spaced. There maybe more than this, however.

I am aware that it is not new, broadly, to provide a pot-hole with aregister similar to au ordinary register for heaters, and this I do notclaim; nor will such a construction fulill the conditions required, forthe reason that it has no independent slides and cannot be employed inheating very small utensils.

Having thus described my invention, I claim-` 1. The combination, withthe cover provided with a circular recess in its upper face and withapertures in the bottom of said recess, of independent slide-platesmounted in said recess and adapted to cover said apertures, whereby saidapertures may be opened or closed independently of each other,substantially as set forth.

2. The combination, with the cover A, provided with a circular recess,a, in its upper face, with apertures a' in the bottom of said recess,and with an annular recess, a, of the slide-plates B B, each providedwith aflange, b, and said plates arranged in said recesess, as shown,and the keeper-plate secured to plate A, and its margin projecting outover the iianges b on said slide-plates, substantially as set forth.

8. The combination, with the recessed and apcrtured cover A, providedwith the annular groove a, of the slide-plates mounted in the recess insaid cover and provided with fianges b in their margins which rest insaid groove a3, substantially as set forth.

4. Ihe combination, with the slide-plate B, provided with the step-likeiiange b 011 its inner margin, of the cover A, properly recessed, asdescribed, to receive said hanged plate,said step-like flange serving tostrengthen said plate and prevent it from warping.

5. The cover A, provided with pendent projections a5, three or more, onits outer margin, whereby an air-space is provided around the edge ofthe cover, said projections also serving as chipping-pieces,substantially as described.

6. The combination of the cover A, provided with the recesses andapertures, substantially as described, the slide plates mounted on saidcover and in said recesses, the keeper-plate C, the attaching-screw c,and the recessed nut c,whereby said keeper-plate may be convenientlyremoved.

7. The combination of the cover A, provided with recesses a a2 in itsupper face, with apertures a', and with a guideflange, a, at its margin,of the slide-plates B B', mounted in the said recesses, and aremovablekeeper-plate, C, secured to said plate A and projecting over the innerends of said slideplates, substantially as set forth.

8. The combination of the recessed cover provided with apertures a andwith stops a, extending radially across the recess between saidapertures, of the sliding plates mounted in said recess between saidstops, substantially as set forth.

9. The combination of the recessed cover A, provided with twosector-shaped apertures, a', and two radially-arranged rib-like stops,a, which divide the recess a into two parts, of the two sectorshapedplates B B', mounted one in each part of said recess a, and means forretaining said plates in the rccesses in the cover, substantially as setforth.

10. The recessed cover provided with apertures a', and with guide-ribs aa on its lower face, arranged substantially as and for the purposes setforth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
